Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus SAS A300 B4–600, B4–600R, 

and F4–600R series airplanes, and 

Model A300 C4–605R Variant F 

airplanes (collectively called Model 

A300–600 series airplanes). This AD 

was prompted by a determination that 

new or more restrictive airworthiness 

limitations are necessary. This AD 

requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective March 7, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 7, 2024. 

ADDRESSES: 

AD Docket: You may examine the AD 

docket at regulations.gov under Docket

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus SAS Model A300– 

600 series airplanes. The NPRM 

published in the Federal Register on 

October 2, 2023 (88 FR 67685). The 

NPRM was prompted by AD 2023–0091, 

dated May 5, 2023, issued by EASA, 

which is the Technical Agent for the 

Member States of the European Union 

(EASA AD 2023–0091) (also referred to 

as the MCAI). The MCAI states that new 

or more restrictive airworthiness 

limitations have been developed. 

EASA AD 2023–0091 specifies that it 

requires certain tasks (limitations) 

already in Airbus A300–600 

Airworthiness Limitations Section 

(ALS), Part 2 DT–ALI, Revision 03, that 

is required by EASA AD 2019–0090, 

dated April 26, 2019 (which 

corresponds to FAA AD 2019–21–01, 

Amendment 39–19767 (84 FR 56935, 

October 24, 2019) (AD 2019–21–01)), 

and that incorporation of EASA AD 

2023–0091 invalidates (terminates) prior 

instructions for those tasks. This AD 

would therefore terminate the 

limitations required by paragraph (g) of 

AD 2019–21–01, for the tasks identified 

in the service information referred to in 

EASA AD 2023–0091 only. 

In the NPRM, the FAA proposed to 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, as 

specified in EASA AD 2023–0091. The 

FAA is issuing this AD to address 

fatigue cracking, damage, or corrosion in 

principal structural elements, which 

could result in reduced structural 

integrity of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1895. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

FedEx and DonZel Culver. Both 

commenters supported the NPRM 

without change. 

Conclusion 

This product has been approved by 

the aviation authority of another 

country and is approved for operation in 

the United States. Pursuant to the FAA’s 

bilateral agreement with this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

reviewed the relevant data, considered 

the comments received, and determined 

that air safety requires adopting this AD 

as proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on this product. Except for 

minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2023–0091 specifies new or 

more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. This material is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section.

6412 Federal Register / Vol. 89, No. 22 / Thursday, February 1, 2024 / Rules and Regulations 

Costs of Compliance 

The FAA estimates that this AD 

affects 128 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. Therefore, the agency 

estimates the average total cost per 

operator to be $7,650 (90 work-hours × 

$85 per work-hour). 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–600, 

737–700, and 737–800 series airplanes. 

This AD was prompted by an evaluation 

by the design approval holder (DAH) 

indicating the fuselage skin repairs at 

the double row of fasteners centered on 

certain stringers have inadequate 

inspection requirements for continuing 

airworthiness following repair 

accomplishment. This AD is intended to 

complete certain programs to support 

the airplane reaching its limit of validity 

(LOV). This AD requires repetitive 

inspections for cracks of skin repairs at 

Stringer S–17, and corrective actions if 

necessary. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

DATES: This AD is effective March 7, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 7, 2024.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

(Boeing) Model 737–600, 737–700, and 

737–800 series airplanes. The NPRM 

was published in the Federal Register 

on May 25, 2023 (88 FR 33849). The 

NPRM was prompted by an evaluation 

by the DAH indicating the fuselage skin 

repairs at the double row of fasteners 

centered on certain stringers have 

inadequate inspection requirements for 

continuing airworthiness following 

repair accomplishment, which could 

result in fatigue cracking of the repair 

going undetected. 

In the NPRM, the FAA proposed to 

require repetitive inspections for 

cracking of the skin repairs at S–17, and 

corrective actions if necessary. The FAA 

is issuing this AD to address this fatigue 

cracking, which, if not addressed, could 

grow to a critical length and result in 

rapid decompression and loss of the 

airplane’s structural integrity. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from the 

Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

The FAA also received comments 

from Aviation Partners Boeing (APB), 

Boeing, Southwest Airlines (Southwest), 

and SunExpress Airline (SunExpress). 

Compliance With AMOC Procedures 

APB determined that the 

incorporation of supplemental type 

certificate (STC) ST00830SE for 

installation of split scimitar winglets 

affects compliance with the mandated 

actions in the proposed rule, but the 

extent of the impact to compliance is 

not fully known at this time. APB noted 

that paragraph (h) of the proposed AD 

would replace the provisions in Boeing 

Service Bulletin 737–53A1217 R1 that 

specify contacting Boeing for an 

alternative method of compliance 

(AMOC) for alternative inspections and 

corrective actions, and instead would 

require using a method approved in 

accordance with paragraph (i) of the 

proposed AD. APB stated that for 

affected airplanes with these winglets, 

approval of any alternative inspections 

and corrective actions for Zone 3 and 

Zone 4 repairs must be obtained from 

the Manager, AIR–520 Continued 

Operational Safety Branch, FAA, 

through the means described in 

paragraph (i)(1) of the proposed AD. 

APB asserted that Boeing does not have 

delegation to approve repairs in areas 

affected by the configuration of STC 

ST00830SE and cannot use ODA 

approval as specified in paragraph (i)(3) 

of the proposed AD. 

The FAA acknowledges APB’s 

comment. Paragraph (h)(1) of this AD 

states that AMOC approval be obtained 

using a method approved in accordance 

with the procedures specified in 

‘‘paragraph (i)’’ of this AD, and does not 

limit approvals to the provisions of 

paragraph (i)(1) or (3) of this AD. 

Therefore, no change to this AD is 

necessary.
